Description

  The present invention relates to a kind of computer lock, and more particularly, to a computer lock that is easy to lock and achieves anti-theft that is convenient for locking.

  As the use of computers has become widespread, notebook computers have come to be used in public places such as libraries, coffee shops, offices, and conference rooms. However, the valuable electronic device itself is firmware, and data provided for internal access cannot be valued. These data are often essences that users have devised over the years, and once a notebook computer (or computer) has been stolen, it can lead to immense loss and inconvenience in work. It is. In particular, in public places, users are exposed to the risk of theft when they leave their seats for several minutes. For this reason, there are various types of computer lock products on the market, which enables the user to prevent the computer from being stolen. Many of these computer locks are protected by patents, for example, Patent Documents 1 and 2 (hereinafter referred to as the previous proposal).

  In the above-mentioned proposal, the locking operation is performed by inserting a cross member 11 at the front end of the lock body into the rectangular anti-theft hole 12 of the case of the computer 10 (as shown in FIG. 1). Turn and drive the horizontal component 11 and rotate it 90 degrees to bring the anti-theft hole 12 into a vertical state and simultaneously drive a pair of parallel pins 13 to hold both sides of the horizontal component 11 This achieves the purpose of the lock (as shown in FIG. 2).

However, although these previous structures can achieve the anti-theft effect, they also have the following problems.
1. The user holds the lock body with one hand and inserts the lateral part 11 into the anti-theft hole 12, and then rotates the lateral part 11 by 90 degrees by rotating the key with the other hand. Two parallel pins 13 are extended forward to sandwich both sides of the sideways component 11. During the rotation process, there is nothing to be locked in the anti-theft hole 12, so that when the key is rotated, the vertical position cannot be maintained between the lock body and the anti-theft hole 12. If an oblique situation occurs, the pin 13 extending outward cannot be blocked by the outside of the anti-theft hole 12 and cannot enter, so that an incomplete lock situation occurs, and it is necessary to lock again and adjust the insertion angle.
2. When a person unfamiliar with the locking operation encounters the situation of the first point described above, the edge of the anti-theft hole 12 is easily damaged because it is forcibly inserted into the inside. A relatively large gap is generated at the hole edge, increasing the risk of being pry open.

At the same time, since the spring 5 is released from the compression, its elasticity is restored and the lock is released. After the tongue sheet 4 is pushed and retracted and the lock tongue 41 is withdrawn from the anti-theft hole 91, the hook portion 611 of the front pillar 61 is further moved, and the locking to the anti-theft hole 91 is released, thus unlocking. Complete the removal operation.

  In summary, the present invention uses a design in which one side is locked to the inner wall surface of the anti-theft hole, and can be performed near the computer case during the locking operation, and the known insertion angle is distorted and the locking operation is affected. Overcoming and easily achieving locking and anti-theft effects.

  The above description is only an example of the present invention, and does not limit the scope of the present invention. Any equivalent changes and modifications that can be made based on the scope of the claims of the present invention are all described in the present invention. Shall belong to the scope covered by the rights.
